Features The TMC246 / TMC246A (1) is a dual full bridge driver IC for bipolar stepper motor controlapplications. The integrated unique sensorless stall detection (pat. pend.) StallGuard™ makes it a good choice for applications, where a reference point is needed, but where a switch is not desired. Its ability to predict an overload makes the TMC246 an optimum choice for drives, where a high reliability is desired. The TMC246 is realized in a HVCMOS technology combined with Low-RDS-ON high efficiency MOSFETs (pat. pend.). It allows to drive a coil current of up to 1500mA even at high environment temperatures. Its low current consumption and high efficiency together with the miniature package make it a perfect solution for embedded motion control and for battery powered devices.Internal DACs allow microstepping as well as smart current control. The device can be controlled by a serial interface (SPI™i) or by analog / digital input signals. Short circuit, temperature, undervoltage and overvoltage protection are integrated.
